"Top seven obscure musical genres allegedly invented in 2012. "Old Guard music writers are still enthralled with this newfangled dubstep noise, but Beatport lurkers have already moved on to a more brash, hyperactive sound called tcrap"

Genres are stupid, arbitrary, and created in hindsight. I used to work at a paleolithic retail workspace called a record store. It was my belief then as it is now that the only division of recordings should be between classical and everything else. And that division is only because the classical world is usually organized by composer rather than performer.

I guess I'll throw Glitch-hop out there, it's decent. Most of these things are sub-genres though, hip-hop is pretty much the last genre invented, everything else has been a sub genre of something else.

I clicked forward in all of these examples looking for something truly innovative. I look back at the dubstep thing; it's electronica with a drop. And the drop has been done in many ways many times before. Wake me up when someone does something new.

Drill: Basically a more proudly ignant version of gangsta rap. It's what would happen if Based God was a thug. Hardly a new sub genre within hip-hop, except that I guess it's a regional thing. Chicago gangsta crunk?

Trap: Hip-hop and EDM have been mixed together from the beginning but this appears to be more about mixing gangsta southern rap with downtempo EDM. I kind of like the song I heard but I always liked downtempo and hip hop influenced EDM.

Hipster House: Oh boy, whatever I just heard sounded very dated, basically just old house. I know hipsters idolize the 80s but that was nothing new at all.

Ratchet: I guess a term created to identify music influenced by hyphy and crunk.

Queer Rap: Gangstalicious come to life or maybe what Lil Wayne really wants to be. Anyway, the song wasn't bad but him being gay was the only reason they would say dude was part of the gay rap genre. It's like saying there is a genre called female rap or something. Good that these guys are breaking that barrier in hip hop though.

Tumblr Wave: The worst thing I've heard in a while. Just awful and there is nothing redeeming about it, well maybe the beat but not really.

Seapunk: Sounds like 90s EDM but I guess the whole point of the genre is that they go on virtual sea journeys or something. Probably requires psychedelics to understand fully.

Americans probably think K-pop was invented this year. And in a related note, I cannot stop listening to Right Now. Seriously, it's been on repeat for a goddamn hour now. It's an awesome song once you learn what the lyrics supposedly mean.

Oh, and the only real genres there are Trap and Seapunk. The rest are just pseudonyms and/or one artist making the stuff and self-designating it (one artist does not a genre make. There has to at least be one label dedicated to making it).

Seapunk is a genre in the Chiptune family that mixes video game chipsets with indie rock/shoegazer (think Crystal Castles, etc.).

Trap is a real thing - it's where all the Bass music guys went (Rick Ross, etc.) when they got sick of Moombahton which replaced Crunk.

There's a logical progression to genres when you break everything down, and any specified genre really only has a lifespan of about 3-5 years, tops, before it evolves into something else or splits off into child genres.
